Confirm the roof can accept restoration
Commercial roof coatings can renew the protective surface of compatible low-slope systems and help extend service life when the roof below remains a sound restoration candidate. The evaluation must begin with the existing material, moisture, adhesion, drainage and repair history.
Condition and diagnosis
Preparation can include cleaning, removal of loose material, compatible repairs, reinforcement at seams or details and correction of conditions that would prevent adhesion. Walls, curbs, penetrations, drains, scuppers and edges should be part of the scope rather than treated as incidental brush work.
Repair, restoration or replacement
Coating should not be used to conceal wet insulation, unstable substrate, widespread detachment or structural drainage problems. Those conditions need a different repair or replacement plan. The estimate should state any testing or opening assumptions and how discoveries affect the proposed restoration boundary.
What a complete proposal should define
Owners should compare material, preparation, application requirements, reinforced details, measured quantities, access, protection and closeout. A coating name by itself does not describe the work required to produce a dependable restored assembly.
